I currently use my HTPC as my only source of TV with the Ceton InfiniTV PCI-E w/ cable card from Mediacom. I haven't touched the hardware on this machine for awhile and wanted to see how I am sitting. Picture's are mostly smooth, maybe once an hour I'll see pixels as a picture lags for maybe a second and then its fine. No issues on watching recorded tv and fast forwarding or anything.
Also, I have the desire to see what 3D pictures can look like on my new TV which is capable, what kind of video card should I think about for that?
Here is the setup:
Intel i5 750 @ 2.67Ghz
HD 5670 512 MB
1 TB 7200 RPM hard drive
I'm not worried about space because I have a 4 TB network attached storage (NAS), that I transfer movies over to.
